What to know
The milk cows in Nevada are infected with bird flu, the USDA’s health inspection of plants of the National Veterinary Service communicated in the statement on Wednesday.
After the implementation of the “entire sequence of genomes” on the selection of cows, Nevada, the USDA concluded that the animals had a new bird flu strain not reported in cows, Klade H5N1, Genotype D1. This is a predominant genotype bird flu worldwide, which is mainly identified in wild birds and poultry during the fall and winter.

The strain also hurt 67 people and caused one death. Since the outbreak started in 2022. years, all 50 states reported infections and hundreds of millions of birds were affected.
The identification of new stress followed the State Monitoring and initial testing within the Code of Milk Testing Strategy, which came out of the December account to monitor the spread of bird flu in milk cows.
